摘要

Abstract

With a growing population

an increasing number of petrochemical facilities are built with larger capacity and more complexity

which pose a great risk to assets

community and environment. The value of inherently safer design is recognized with time by all stakeholders

and an effective tool is needed to evaluate and compare inherent safety of alternative technologies. This study developed a safety index to evaluate existing technologies for their safety levels and guide inherently safer design. The Integrated Risk-based Safety Index (IRSI) was developed based on a comprehensive review of petrochemical processes

incident cases from Sinopec and US Chemical Safety Board

and existing safety index systems. The IRSI included all major hazards

including fire

explosion

toxic release

dust explosion

physical explosion

and runaway. Also

the integrated life cycle approach considered chemical hazards

equipment failure rates and safety measures in this risk-based index. Advanced modeling techniques

PHAST simulation and Neural Network

were used in the development of three novel sub-indices in the projects

fire

explosion and toxic release. The index system could be easily incorporated into a user friendly tool for the ease of application. A case study of hydrogen dioxide was conducted using the IRSI

which showed its capability for evaluating the safety level of process facilities.
